Germany's CDU-SPD coalition cabinet approved a draft Building Modernization Act submitted by ministers Verena Hubertz and Katherina Reiche that sets a 10% renewable energy requirement for new heating systems and extends flexibility for oil and gas systems in existing buildings. The legislation is intended to replace the previous Heating Act's 65% renewable mandate and is targeted for parliamentary passage before the mid-July recess. Power prices have shown extreme daily volatility according to separate reporting.
